How much concrete goes into building a nuclear reactor



How much steel and how much concrete

for the fabrication of windmills and nuclear reactors ?

| |EPR nuclear reactor |Typical modern windmill |

|Power |1 600 MW |2 MW |

|Coeff production (h/an) |7000 h (80% of 8760 h) |1750 h (20% of 8760 h) |

|Life time |60 years |15 years |

|Total production in TWh |670 TWh |0,053 TWh |

|(over entire lifetime) | | |

|Tons of steel |40 000 |150 |

|Tons of concrete |200 000 |1000 |

|Tons of steel per TWh |60 tons of steel per TWh |2830 tons of steel per TWh |

|Tons of concrete per TWh |300 tons of concrete per TWh |18900 tons of concrete per TWh |

For the same amount of electricity produced, windmills require 50 times more steel and 60 times more concrete than nuclear reactors.

This is with the EPR reactor which is a rather “heavy” reactor (more steel and concrete than its’ competitors, such as the AP-1000).
